Global Error Handling

Error handling for API calls involves wrapping requests in try-catch blocks, logging failures, and returning user-friendly messages instead of technical errors. Implement retry logic with exponential backoff for transient failures, and ensure the application degrades gracefully rather than crashing when external APIs fail.

Use centralized error handling boundaries with explicit exception types to catch and process errors consistently. This approach prevents cascading failures, enables proper resource cleanup, and ensures secure, user-facing messages that don't expose internal system details or sensitive information.

Transform technical exceptions into clear, actionable messages by removing internal details and system jargon. Provide context about what failed and next steps the user can take, such as retry options or alternative actions, while keeping sensitive technical information in server logs only.

Retry logic with exponential backoff handles transient failures in external APIs and services by automatically re-attempting requests with increasing delays. This improves resilience and user experience by recovering from temporary outages without exposing errors to end users.

Yes. Error handling applies to database operations by catching exceptions, ensuring proper resource cleanup through try-finally blocks or cleanup handlers, and implementing failure-fast behavior to prevent resource leaks and data corruption.

Internal logging captures full technical details for debugging and monitoring, while user-facing messages communicate only necessary information in plain language. This separation prevents information disclosure vulnerabilities and improves user experience by avoiding cryptic error codes.
